Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a remote controller structure for a bubble generating bath.

(B) Conventional technology As an example of a conventional bubble-generating bath, a bath hot water circulation passage is provided between a bath body and a circulation pump, and an air intake portion is connected to the bath hot water circulation passage. In some cases, the bath water containing bubbles can be jetted into the bathtub body, and the number of revolutions of the circulation pump can be controlled by the control unit to adjust the jetting amount of the bath hot water containing bubbles.

The operation of the circulation pump via the control unit can be easily performed by the remote controller even in the bathing posture.

The remote controller has a waterproof structure made of synthetic resin so that the remote controller can be used in a place where hot water is constantly applied.

(C) Problems to be solved by the invention However, if the remote controller has a completely waterproof structure in order to ensure waterproofness, the remote controller may be accidentally immersed in hot bath water or When a high-temperature shower is applied, the air inside the remote controller expands due to heat, and the strength of the synthetic resin material that forms the remote controller case decreases, causing the case to swell and plastically deform. There is a problem of doing.

Further, if the thickness of the case is increased to increase the strength in order to prevent the case from being deformed, there is a problem that the weight of the remote controller becomes heavy and it becomes difficult to operate.

Further, when forming the case, there is a problem such as shrinkage strength (so-called sink mark) of the synthetic resin due to increase in wall thickness.

(D) Means for Solving the Problems In the present invention, therefore, a circulation pump is capable of ejecting hot water containing air bubbles into the bathtub body, and the circulation pump is operable via a control unit. A remote controller for an air bubble generating bath, which is a free-flowing remote controller and is enclosed in a space inside the remote controller with a light-weight encapsulating material such as synthetic rubber or polyethylene resin, which has a smaller expansion coefficient than air. It is intended to provide structure.

(E) Action / Effect According to the present invention, the following action / effect is produced.

That is, in the present invention, since the control unit for controlling the rotation speed of the circulation pump can be operated by the portable remote controller, the bather can take a bath while holding the remote controller in his / her hand and take a relaxing bath. By operating the remote controller while keeping the posture, the circulation pump can be controlled via the control unit, and the ejection amount of the bath water containing bubbles can be adjusted according to preference.

At this time, the remote controller has a closed structure to ensure waterproofness, and the space inside the remote controller is filled with a light-weight encapsulating material such as synthetic rubber or polyethylene resin that has a smaller expansion coefficient than air. Since the absolute amount of air in the remote controller is small, it is possible to prevent the deformation of the remote controller due to expansion by minimizing the pressure rise in the remote controller due to thermal expansion of air. it can.

Moreover, since the encapsulating material is lightweight and has a smaller expansion coefficient than that of air, there is no problem that the encapsulating material expands and deforms the remote controller, and it is possible to secure a weight reduction such that the remote controller itself floats on water.

Further, the independent foaming filler can enhance the impact resistance and vibration resistance of the electric circuit section provided in the remote controller.
